Expressive Attribute-Based Encryption with Constant-Size Ciphertexts from the Decisional Linear Assumption
attribute-based encryption constant-size ciphertexts decisional linear assumption
2016/1/25
We propose a key-policy attribute-based encryption (KP-ABE) scheme with constantsize
ciphertexts, whose semi-adaptive security is proven under the decisional linear (DLIN)
assumption in the standard...
Bilinear Entropy Expansion from the Decisional Linear Assumption
Cryptographic Protocols Attribute Based Encryption Decisional Linear Assumption
2016/1/7
We develop a technique inspired by pseudorandom functions that allows us to increase
the entropy available for proving the security of dual system encryption schemes under
the Decisional Linear Assu...
Fully Secure Functional Encryption with General Relations from the Decisional Linear Assumption
Functional Encryption Attribute-Based Encryption Predicate Encryption
2010/11/10
This paper presents a fully secure functional encryption scheme for a wide class of relations, that are specified by non-monotone access structures combined with inner-product relations. The security ...
Efficient Pseudorandom Functions From the Decisional Linear Assumption and Weaker Variants
Efficient Pseudorandom Functions Decisional Linear Assumption Weaker Variants
2009/10/9
In this paper, we generalize Naor and Reingold's construction of pseudorandom
functions under the DDH Assumption to yield a construction of pseudorandom
functions under the decisional k-Linear Assum...
